This study aims to create a systematic decision-making framework for designing children’s scooters by integrating AHP, CRITIC, and VIKOR methodologies.
Field investigations and questionnaires identify user requirements.
A multi-level evaluation indicator system is constructed.
AHP determines subjective weights, while CRITIC balances objective data for design evaluation.
Safety-related factors are prioritized, with material safety and braking performance being crucial.
The optimal design scheme aligns closely with the ideal solution.
Sensitivity analysis confirms the robustness of the proposed decision-making model.
